  • how to open many tabs in chromium but unload/disable inactive/notCurrent ones, releasing memory and cpu?

    - by Aquarius Power
    So I have 50 tabs opened on chromium, but that is using too much memory and some of the CPU. How can I have all those concurrent researches I am doing opened but not clog my machine? I think there should have a way that only the active tab is loaded in memory and running, and all the others should stay closed/unloaded from memory, until I want to look at them... Any extension can do something like that?

  • gtk+ checkbutton settings

    - by jldupont
    Is there a way to use set_active on a gtkCheckButton but without the user being able to press/toggle the said button? In other words, I want to programmatically control the active state of the CheckButton but I don't want the user to be able to change it.

  • CSS: a:link vs just a (without the :link part)

    - by Rob
    So we're required to use the following order for CSS anchor pseudo-classes a:link { color: red } a:visited { color: blue } a:hover { color: yellow } a:active { color: lime } But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over: a { color:red; } /* notice no :link part */ a:visited { color: blue; } etc.,etc.

  • How to disable current page links in ASP.NET MVC?

    - by rem
    I'm investigating ASP.NET MVC now and noticed that in ASP.NET MVC application, which is created by Visual Studio by default, links "Home" and "About" are staying active when the user is on "Home" and "About" page correspondingly, and after clicking on the current page link page is reloading itself. What is the correct approach to disable link which points to the page, a user is already on? How to do it without violating ASP.NET MVC approach?

  • Server-environment and configuration: How bad is fread() etc?

    - by zero
    Hello dear commmunity, good day! I run a little site (now for several months ) that has users accessing big files, for download as well for streaming to the browser. It's fairly active, so assuming the worst, how bad is getting php to read the files that would be stored outside of the webroot and then getting it to echo it to a page dynamically for the browser to then read? My question is: how bad is fread() etc in this context!? zero

  • SCOM 2012 DNS Forwarder Availability Monitor

    - by Massimo
    Background: I have an environment with two different AD domains, each in its own forest, each with two Windows Server 2008 R2 domain controllers acting as DNS servers. There is no trust between the domains. Each DNS server manages the main DNS zone for its AD domain, and then some other zones, including the reverse lookup zone for its IP subnets; all zones are AD-integrated; all DNS servers which manages a zone are correctly listed as authoritative name servers for that zone. So, the situation is like this (using fake names and IP addresses): Domain A: DNS domain: a.dom IP subnet: 192.168.1.X DC/DNS Servers: serverA1.a.dom (192.168.1.1) and serverA2.a.dom (192.168.1.2) Authoritative zones: a.dom, 1.168.192.in-addr.arpa, somezone.local Domain B: DNS domain: b.dom IP subnet: 10.0.0.X DC/DNS Servers: serverB1.b.dom (10.0.0.1) and serverB2.b.dom (10.0.0.2) Authoritative zones: b.dom, 0.0.10.in-addr.arpa, someotherzone.local DNS servers in domain A have conditional forwarders defined for each zone managed by DNS servers in domain B, forwarding to both domain B's DNS servers; DNS servers in domain B have the opposite configuration. All forwarders are stored in Active Directory. All is working perfectly, and computers in each domain can resolve forward and reverse DNS queries for both domains, using their domain's DNS servers. The problem: I have SCOM 2012 deployed in domain A, with the SCOM agent installed on both DCs; the management packs for Active Directory and DNS Server are installed and up-to-date. I have a series of alerts like the following ones on both domain controllers; each alert is generated for each forwarded zone and for each forwarded server: Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.1,someotherzone.local for serverA1.a.dom Forwarder someotherzone.local (10.0.0.1) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder someotherzone.local (10.0.0.2) cannot resolve the host name 192.168.1.2,someotherzone.local for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.1,0.0.10.in-addr.arpa for serverA1.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.1) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom Forwarder 0.0.10.in-addr.arpa (10.0.0.2) cannot resolve the host name 192.168.1.2,0.0.10.in-addr.arpa for serverA2.a.dom The only exception is the main AD DNS zone managed by domain B's DNS servers (b.dom): for that conditional forwarder, no alert is generated and the forwarder availability monitor is green. Ok, what does this mean? What are those monitors trying to tell me? What are they checking? What's actually wrong? And why there is no error for the "b.dom" zone, which is configured in the exact same way as the other ones, both as a zone in domain B's DNS servers and as a forwarder in domain A's DNS servers?

  • Postfix - am I sending spam?

    - by olrehm
    today I received like 30 messages within 5 minutes telling me that some mail I send could not be delivered, mostly to *.ru email addresses which I did not send any mail to. I have my own webserver (postfix/dovecot) set up using this guide (http://workaround.org/ispmail/lenny) but adjusted a little bit for Ubuntu. I tested whether I am an Open Relay which I am apparently not. Now there are two possible reasons for the above mentioned emails: Either I am sending out spam, or somebody wants me to think that, correct? How can I check this? I selected one particular address that I supposedly send spam to. Then I searched my mail.log for this entry. I found two blocks that record that somebody from the server connected to my server and delivered some message to two different users. I cannot find an entry reporting that anyone from my server send an email to that server. Does this mean its just some mail to scare me or could it still have been send by me in the first place? Here is one such block from the log (I replaced some confidential stuff): Jun 26 23:23:28 mycustomernumber postfix/smtpd[29970]: connect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: 044991528995: client=mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/cleanup[29974]: 044991528995: message-id=<[email protected]> Jun 26 23:23:29 mycustomernumber postfix/qmgr[3369]: 044991528995: from=<>, size=2198, nrcpt=1 (queue active) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) ESMTP::10024 /var/lib/amavis/tmp/amavis-20110626T223137-28598: <> -> <[email protected]> SIZE=2198 Received: from mycustomernumber.stratoserver.net ([127.0.0.1]) by localhost (rehmsen.de [127.0.0.1]) (amavisd-new, port 10024) with ESMTP for <[email protected]>; Sun, 26 Jun 2011 23:23:29 +0200 (CEST) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) Checking: YakjkrdFq6A8 [195.144.251.97] <> -> <[email protected]> Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: disconnect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) lookup_sql_field(id) (WARN: no such field in the SQL table), "[email protected]" result=undef Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: connect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: 0A1FA1528A21: client=localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/cleanup[29974]: 0A1FA1528A21: message-id=<[email protected]> Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: from=<>, size=2841, nrcpt=1 (queue active) Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: disconnect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) FWD via SMTP: <> -> <[email protected]>,BODY=7BIT 250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21 Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) Passed CLEAN, [195.144.251.97] [195.144.251.97] <> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: YakjkrdFq6A8, Hits: 2.249, size: 2197, queued_as: 0A1FA1528A21, 2882 ms Jun 26 23:23:32 mycustomernumber postfix/smtp[29975]: 044991528995: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.3, delays=0.39/0.01/0.01/2.9, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21) Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 044991528995: removed Jun 26 23:23:33 mycustomernumber postfix/smtp[29980]: 0A1FA1528A21: to=<[email protected]>, orig_to=<[email protected]>, relay=mx3.hotmail.com[65.54.188.110]:25, delay=1.2, delays=0.15/0.02/0.51/0.55, dsn=2.0.0, status=sent (250 <[email protected]> Queued mail for delivery) Jun 26 23:23:33 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: removed Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection rate 1/60s for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection count 1 for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max cache size 1 at Jun 26 23:23:28 I can provide more info if you tell me what you need to know.

  • AdPrep logs show an LDAP error

    - by Omar
    What I am trying to do is transition our domain from Server 2003 Enterprise x32 to Server 2008 R2 Enterprise x64. Here is what I have done thus far. The 2003 server is a physical machine, the 2008 server is a virtual machine Built a virtual machine that has Server 2008 R2 Enterprise x64 and joined it to the domain as a domain member On the 2003 DC, Raised Domain Functional Level and Forest Functional Level to Windows Server 2003 On the 2003 DC, went into the registry and navigated to HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters and verified that the Schema Version is 30 On the 2003 DC, inserted the Windows Server 2008 Enterprise x32 Edition to copy over the adprep folder. This version is the only one that seemed to work On the 2003 DC, opened command prompt and went to adprep directory and ran adprep /forestprep , adprep /domainprep , and adprep /domainprep /gpprep On the 2008 server, Installed the Active Directory Domain Services role from Server Manager On the 2003 DC, went into the registry and navigated to HKLM\SYSTEM\CurrentControlSet\Services\NTDS\Parameters and verified that the Schema Version is now 44 When I go to run dcpromo on the 2008 server, I get a message that says: "To install a domain controller into this Active Directory forest, you must first prepare using adprep /forestprep" I went back to the 2003 DC server and went through the adprep logs and I came across this: Adprep was unable to modify the security descriptor on object CN=DomainControllerAuthentication,CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=xeroxtoledo,DC=com. [Status/Consequence] ADPREP was unable to merge the existing security descriptor with the new access control entry (ACE). [User Action] Check the log file ADPrep.log in the C:\WINDOWS\debug\adprep\logs\20100327143517 directory for more information. Adprep encountered an LDAP error. *Error code: 0x20. Server extended error code: 0x208d, Server error message: 0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of: 'CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=xeroxtoledo,DC=com* In fact, I got three of these errors. The LDAP error is consistent with all three, but the top part where it says "Adprep was unable to modify the security descriptor on object" are different. They are the following: CN=DomainControllerAuthentication,CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=xeroxtoledo,DC=com. CN=DirectoryEmailReplication,CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=xeroxtoledo,DC=com. CN=KerberosAuthentication,CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=xeroxtoledo,DC=com. The credentials I am using on the 2008 server when running dcpromo is my domain account. My account is part of the domain and enterprise admin groups. I've tried various quick fixes that I've came across through Google searches that include: Disabling AntiVirus on current DCs Pointing DNS on PDC to point to itself Changing the Schema Update Allowed key to 1 and tried rerunning adprep - when rerunning adprep, told me that Forest-wide information has already been updated Disabled Windows Firewall on the Server 2008 box On the 2003 DC, went to Domain Controller Security Policy Local Policies User Rights Assignment and added Domain Admins to the Enable computer and user accounts to be trusted for delegation policy setting Both our PDC and BDC are Global Catalog Servers. Not sure if this matters or not I ran the command netdom query fsmo and verified that the FSMO role holder is the current 2003 PDC I ran dcdiag /v on the 2003 PDC and the only thing that failed was Services. Dnscache Service is stopped on the PDC I even went as far as deleting the virtual machine and recreating it from scratch - no avail... Help :(

  • DHCP and DNS services configuration for VOIP system, windows domain, etc

    - by Stemen
    My company has numerous physical offices (for purposes of this discussion, 15 buildings). Some of them are well-connected to our primary data center via fiber. Others will be connected to the data center by P2P T1. We are in the beginning stages of implementing an Avaya VOIP telephone system, and we will be replacing a significant portion of our network infrastructure in the process. In tandem with the phone system implementation, we are going to be re-addressing some of our networks, and consolidating most of our Windows domains into one (not all domains, just most). We currently have quite a few Windows domains, and they of course each have their own DNS zones. A few of those networks currently use DHCP, but the majority use static IP assignments for every device. I'm tired of managing static assignments -- I want to use DHCP configuration on everything except servers. Printers and etc will have DHCP reservations. The new IP phones will need to get IP addresses from DHCP, though they need to be in a separate VLAN from the computers/printers/etc. The computers and printers need to be registered in DNS. That's currently handled by the Windows DHCP servers on each of the respective domains. We need to place a priority on DHCP and DNS being available on a per-site basis (in case something were to interrupt the WAN connection) for computers and (primarily) phones. Smaller locations (which will have IP phones but not be a member of any Windows domain) will not have any Windows DNS/DHCP server(s) available. We also are looking for the easiest way to replace a part if it were to fail. That is to say, if a server/appliance/router hosting DHCP were to crash hard, and we couldn't extremely quickly recover the DHCP reservations and leases (and subsequently restore them onto a cold spare), we anticipate that bad things could happen. What is the best idea for how to re-implement DNS and DHCP keeping all of the above in mind? Some thoughts that have been raised (by myself or my coworkers): Use Windows DNS and DHCP servers, where they exist, and use IP helpers to route DHCP requests to some other Windows server if necessary. May not be acceptable if the WAN goes down and clients don't get a DHCP response. Use Windows DNS (everywhere, over WAN in some cases) and a mix of Windows DHCP and DHCP provided by Cisco routers. Every site would be covered for DHCP, but from what I've read, Cisco routers can't handle dynamic registration of DHCP clients to Windows DNS servers, which might create a problem where Cisco routers are used for DHCP. Use Windows DNS (everywhere, over WAN in some cases) and a mix of Windows DHCP and DHCP provided by some service running on an extremely low-price linux server. Is there any such software that would allow DHCP leases granted by these linux boxes to be dynamically registered on the Windows DNS servers? Come up with a Linux solution for both DNS and DHCP, and deploy low-price linux servers to every site. Requirements would be that the DNS zone be multi-master (like Windows DNS integrated with Active Directory), that DHCP be able to make dynamic DNS registrations in that zone, for every lease (where a hostname is provided and is thus possible), and that multiple servers be either authoritative for the same DHCP scope or at least receiving a real-time copy / replication / sync of the leases table so that if one server dies, we still know which MAC has what address. Purchase dedicated DNS/DHCP appliances, deploying to all sites. From what I read/see, this solves all of our technical problems. Then come the financial problems... I don't have a ton of money to spend on this. Or, some other solution that we've thus far overlooked and will consider upon recommendation. Can Cisco routers or Windows servers sync DHCP lease tables so that multiple servers can be authoritative (or active/passive for all I care) for the same scope, in case one of the partners were to fail? I've read online (repeatedly) that ISC's DHCP is able to maintain the same lease table across multiple servers, in order to solve this problem. Does anyone have any experience or advice to regarding that?

  • How to get rid of a stubborn 'removed' device in mdadm

    - by T.J. Crowder
    One of my server's drives failed and so I removed the failed drive from all three relevant arrays, had the drive swapped out, and then added the new drive to the arrays. Two of the arrays worked perfectly. The third added the drive back as a spare, and there's an odd "removed" entry in the mdadm details. I tried both mdadm /dev/md2 --remove failed and mdadm /dev/md2 --remove detached as suggested here and here, neither of which complained, but neither of which had any effect, either. Does anyone know how I can get rid of that entry and get the drive added back properly? (Ideally without resyncing a third time, I've already had to do it twice and it takes hours. But if that's what it takes, that's what it takes.) The new drive is /dev/sda, the relevant partition is /dev/sda3. Here's the detail on the array: # mdadm --detail /dev/md2 /dev/md2: Version : 0.90 Creation Time : Wed Oct 26 12:27:49 2011 Raid Level : raid1 Array Size : 729952192 (696.14 GiB 747.47 GB) Used Dev Size : 729952192 (696.14 GiB 747.47 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 2 Persistence : Superblock is persistent Update Time : Tue Nov 12 17:48:53 2013 State : clean, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 UUID : 2fdbf68c:d572d905:776c2c25:004bd7b2 (local to host blah) Events : 0.34665 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 19 1 active sync /dev/sdb3 2 8 3 - spare /dev/sda3 If it's relevant, it's a 64-bit server. It normally runs Ubuntu, but right now I'm in the data centre's "rescue" OS, which is Debian 7 (wheezy). The "removed" entry was there the last time I was in Ubuntu (it won't, currently, boot from the disk), so I don't think that's not some Ubuntu/Debian conflict (and they are, of course, closely related). Update: Having done extensive tests with test devices on a local machine, I'm just plain getting anomalous behavior from mdadm with this array. For instance, with /dev/sda3 removed from the array again, I did this: mdadm /dev/md2 --grow --force --raid-devices=1 And that got rid of the "removed" device, leaving me just with /dev/sdb3. Then I nuked /dev/sda3 (wrote a file system to it, so it didn't have the raid fs anymore), then: mdadm /dev/md2 --grow --raid-devices=2 ...which gave me an array with /dev/sdb3 in slot 0 and "removed" in slot 1 as you'd expect. Then mdadm /dev/md2 --add /dev/sda3 ...added it — as a spare again. (Another 3.5 hours down the drain.) So with the rebuilt spare in the array, given that mdadm's man page says RAID-DEVICES CHANGES ... When the number of devices is increased, any hot spares that are present will be activated immediately. ...I grew the array to three devices, to try to activate the "spare": mdadm /dev/md2 --grow --raid-devices=3 What did I get? Two "removed" devices, and the spare. And yet when I do this with a test array, I don't get this behavior. So I nuked /dev/sda3 again, used it to create a brand-new array, and am copying the data from the old array to the new one: rsync -r -t -v --exclude 'lost+found' --progress /mnt/oldarray/* /mnt/newarray This will, of course, take hours. Hopefully when I'm done, I can stop the old array entirely, nuke /dev/sdb3, and add it to the new array. Hopefully, it won't get added as a spare!

  • Chrome does not re-draw properly on Windows 8

    - by Akshat Mittal
    There are a lot of problems with Chrome (24.0.1312.14 beta || But all this happened before update also) on Windows 8. Problems and explanations are listed below: Google Chrome re-draw time: When I switch tabs, the window retains the content of the previous tab and displays that even if I move my mouse, if only refreshes (re-draws) when there is a change on the webpage (like on hover) or I do a select all (or scroll). One thing to note is that the hover and select happens on the real page and not the retained image-like thing of the older webpage. Chrome is slow and laggy: Websites such as Facebook and Twitter (and more) have gone extremely laggy on Chrome (Win 8). When I was using Windows 7, I never experienced a lag or something. Also when using HTML-5 Websites, the transition (the -webkit-transition in CSS) goes extremely slow at times. Plugins Crash: Plugins like Flash Player, Shockwave Player, and more that are in-built into Chrome Crashes a lot, even when doing simple tasks like playing YouTube Videos, displaying ads or something. Chrome Crashes: Chrome has crashed over 100 times in the past month. Google Chrome just crashes randomly or I don't know the reason. Random Page crashes: Chrome results chrome://crash/(Copy-Paste this in address bar) on random pages even when the page is just loaded, I understand that this can happen on heavy HTML5 or JS websites but what about HTML only websites? Computer Freeze: Chrome sometimes, randomly, freezes my computer. Freeze in the sense, none of the other apps are also working. It's like the whole system freezes, I can not even switch to other apps. I am sure that this is because of Chrome since this happens only when Chrome is active. Most of the things above happens on Super User also, Super User never had any problem when using Chrome on Windows 7. UPDATE 1: @magicandre1981 Commented for trying to disable Hardware Acceleration. I tried it, it somewhat solved the problem but din't fix it. I am still experiencing all the above issues but less frequently (maybe because Chrome Restarted Completely) UPDATE 2: @avirk asked me to try a Stable Version of Chrome and Firefox, I din't experience any lag in Firefox, a little (negligible) lag in Chrome 22 (Maybe because its a new copy of Chrome, I haven't used it much). UPDATE 3: @NothingsImpossible said that He is also experiencing the same problem on Windows Server 2008! This seams to be a major issue now. He also said that GPU load is also high at the same time! Even I saw the same thing. UPDATE 4: Recently, Chrome updated to v24 Stable (I am using stable from a long time now). I was experiencing this problem a lot less in Chrome 23, but this is back in Chrome 24. Seams like Chrome 24 is the most affected from this bug, as this same problem was high in Chrome 24 beta also. UPDATE 5: Chrome was updated to v25 Stable. This problem is 99% Gone, it is still there in 1% of the cases. One such example is when I leave chrome inactive for a while with a few tabs open, the tabs go black and no activity can get them back to active state. If I open a new tab, the new tab is OK but the others are still black, I need to close all those tabs. UPDATE 6: Chrome updated to v27 Stable channel, this problem is nearly gone. This does happen occasionally, but not as frequent as in earlier versions of Chrome. UPDATE 7: I am on Chrome v35.0.1916.114 Stable, Windows 8.1 Pro Update 1. Some of the other problems appears to be back. Chrome is slow and laggy again. Re-draw time is getting worse. Is anybody else experiencing such issues? Does anybody have a solution to any of these?

  • No device file for partition on logical volume (Linux LVM)

    - by Brian
    I created a logical volume (scandata) containing a single ext3 partition. It is the only logical volume in its volume group (case4t). Said volume group is comprised by 3 physical volumes, which are three primary partitions on a single block device (/dev/sdb). When I created it, I could mount the partition via the block device /dev/mapper/case4t-scandatap1. Since last reboot the aforementioned block device file has disappeared. It may be of note -- I'm not sure -- that my superior (a college professor) had prompted this reboot by running sudo chmod -R [his name] /usr/bin, which obliterated all suid in its path, preventing the both of us from sudo-ing. That issue has been (temporarily) rectified via this operation. Now I'll cut the chatter and get started with the terminal dumps: $ sudo pvs; sudo vgs; sudo lvs Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Scanning for physical volume names PV VG Fmt Attr PSize PFree /dev/sdb1 case4t lvm2 a- 819.32G 0 /dev/sdb2 case4t lvm2 a- 866.40G 0 /dev/sdb3 case4t lvm2 a- 47.09G 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" VG #PV #LV #SN Attr VSize VFree case4t 3 1 0 wz--n- 1.69T 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all logical volumes LV VG Attr LSize Origin Snap% Move Log Copy% Convert scandata case4t -wi-a- 1.69T Wiping internal VG cache $ sudo vgchange -a y Logging initialised at Sat Jan 8 11:43:14 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" 1 logical volume(s) in volume group "case4t" already active 1 existing logical volume(s) in volume group "case4t" monitored Found volume group "case4t" Activated logical volumes in volume group "case4t" 1 logical volume(s) in volume group "case4t" now active Wiping internal VG cache $ ls /dev | grep case4t case4t $ ls /dev/mapper case4t-scandata control $ sudo fdisk -l /dev/case4t/scandata Disk /dev/case4t/scandata: 1860.5 GB, 1860584865792 bytes 255 heads, 63 sectors/track, 226203 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00049bf5 Device Boot Start End Blocks Id System /dev/case4t/scandata1 1 226203 1816975566 83 Linux $ sudo parted /dev/case4t/scandata print Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/case4t-scandata: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1861GB 1861GB primary ext3 $ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1860.5 GB, 1860593254400 bytes 255 heads, 63 sectors/track, 226204 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000081 Device Boot Start End Blocks Id System /dev/sdb1 1 106955 859116006 83 Linux /dev/sdb2 113103 226204 908491815 83 Linux /dev/sdb3 106956 113102 49375777+ 83 Linux Partition table entries are not in disk order $ sudo parted /dev/sdb print Model: DELL PERC 6/i (scsi) Disk /dev/sdb: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 880GB 880GB primary reiserfs 3 880GB 930GB 50.6GB primary 2 930GB 1861GB 930GB primary I find it a bit strange that partition one above is said to be reiserfs, or if it matters -- it was previously reiserfs, but LVM recognizes it as a PV. To reiterate, neither /dev/mapper/case4t-scandatap1 (which I had used previously) nor /dev/case4t/scandata1 (as printed by fdisk) exists. And /dev/case4t/scandata (no partition number) cannot be mounted: $sudo mount -t ext3 /dev/case4t/scandata /mnt/new mount: wrong fs type, bad option, bad superblock on /dev/mapper/case4t-scandata, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so All I get on syslog is: [170059.538137] VFS: Can't find ext3 filesystem on dev dm-0. Thanks in advance for any help you can offer, Brian P.S. I am on Ubuntu GNU/Linux 2.6.28-11-server (Jaunty) (out of date, I know -- that's on the laundry list).
